IMPROVEMENTIN FVIRE-POTS FOR SOLDERlNG-IRON HEATERS.

Specification forming'part of Letters Patent No. 222,237, dated December2, 1879 application filed August 29, 1879.

To all whom it may concern Be it known that I, JAMES T. BROWN, ofSara-nae, in the county of Ionia. and .State of Michigan, have inventeda new and Improved Fire-Potfor Heating Soldering-Irons, of which thefollowing is a specification.

Figure 1 is a front elevation of the device, partly in section. Fig. 2is a, plan of the same, partly in section. Fig.- 3 is a perspective viewof the fire-pan.

Similar letters of reference indicate corresponding parts.

The object of this invention is to provide'a firepot for heatingsoldering-irons, shoe-makers burnishers, branding-irons, and the like,in a cheap and expeditious manner.

The invention is more especially designed, however, for soldering-irons;and it consists 'of a cylindrical metallic vessel or combustionchamberwith a perforated bottom and side openings fixed centrally within alarger cylinder that is provided with a movable cover and smoke-pipe 5and it further consists of a circular shallow vessel, called agenerator,

that is set in the top of the interior cylinder,

and supplied with oilor gasoline, or other liquid hydrocarbon,through apipe connecting with an elevatedrservoir.

In the drawings, A represents a cylindrical metallic vessel orcombustion-chamber, provided with side apertures, b b, and set upon abase, B, through which are openings at a, for the admission of air, andwhich itself rests upon a platform, 0. Fixed over and around thiscylinder A is the larger cylinder D, provided with a movable cover, E,that carries a smoke-pipe, F.

Fitting within the flanged top of the inner cylinder, A, is thegenerator G, which is a shallow circular vessel, in which is ahorizontal diaphragm, d, supported on rods projecting upward from theflat bottom of the generator, A short tube, f, closed at its lower end,but provided with a minute orifice, projects centrally downward from theflat bottom of the generator, and from its convex upper surface the pipeH, provided with cock 9, connects with the hydrocarbon-reservoir I, thatis supported on a standard, K. The lower part of this pipe Hisfittedwith a wick, h.

To operate the device a small quantity of oil is put in the pan L, whichis then placed within the smaller cylinder, A, through the frontopening, 8, and set on fire. Thecockgis then turned to permit a smallquantity of the hydrocarbon to flow into the generator G upon thediaphragm (1, when the heat from the burning oil in the pan quicklyconverts this liquid hydrocarbon in the generator Ginto gas, whichforces its way out through the minute opening in the end of the tube fand takes fire, and the flame and smoke therefrom tend downward to theside apertures, b b, and thence upward to the smoke-pipe.

Sufficient air for complete combustion is supplied through theperforations a a and the openings 0, which latter may be opened orclosed with slides or doors nw, to regulate the admission of the air.The diaphragm 01 serves to spread the oil supplied tothe generator G, sothat it (the oil) may present a maximum of evaporation-surface.

The wick h, by filling the tubes diameter, assists in regulating theflow of the oil, and to make the apparatus secure against explo sion. Assoon as gas is generated and is burn ing, the pan L is withdrawn, andthe soldering or other irons to be heated are thrust into the fire-pot Athrough the front opening, 8, their handles resting on the rod M. Itisfound in practice that the smoke from the burning gas or oil is sodirectly carried 011' through the side openings in the fire-pot, asshown by the arrows in Fig. 1, that it does not come at all in contactwith the points of the irons, which quickly heat and keep bright andclean.

To prevent the heat from burning the plat form C, a shield, N, is placedbetween it and the bottom of the fire-pot A.

It is found that great economies in time and in cost of fuel are securedby the use of this device, and that it can be used and manipu lated withperfect success by any workman.

Having thus fully described my invention, I claim as new and desire tosecure by Letters Patent 1.
